1.4 Safety warnings

We recommend you consult the technical manual of the machine before performing any mainte-nance work.Observe all applicable standards relating to the repair of electrical appliances.

Always disconnect the power plug from the mains before beginning repair work.Simply turning off the main machine power switch is not an adequate safety precaution.

This domestic appliance is rated as insulation class I.On completion of the repair work, insulation and dielectric rigidity tests must be performed.

4.2. Coffee cycle

Switching onWhen the machine is switched on, the gear motor repositions itself as follows:- It acts on microswitch 1 (see following chapter).- The gear motor changes its rotation direction and moves upwards again by approx. 1-2 mm.- The boiler begins to heat the water for approx. 45 sec., at full power, in order to reach the

optimal temperature. The temperature will then remain at a constant level.

Coffee cycleThe coffee grinder starts the grinding process (controlled by pulses generated by a sensor).1. The gear motor (brewing unit) moves to the brewing position.2. Preliminary dispensing phase (short pump activity, short pause).3. Product dispensing (the pump operation period is defi ned by the amount of product dis-4. pensed).The gear motor moves to its home position (the dregs are expelled automatically).5.

An NTC is used as a temperature sensor; in the event of overheating this reduces boiler element power consumption.The electronic system detects the current boiler temperature from the drop in voltage of the sensor and adjusts it accordingly.Heating element values and corresponding temperatures: see table.

4.3. Single microswitch

The gear motor is powered by a direct cur-rent motor that engages with the smaller double toothed wheel using a worm screw. The unit is mounted on the axle of the large gear wheel and when a coffee is requested, it moves from the standby position to the dis-pensing position, and then back to the stand-by position again.

Without beans n=100%

The coffee grinder is driven by a direct current motor (1) using a worm screw helicoidal wheel transmission (2).The worm screw (2) drives a plastic gear wheel (3), which turns the lower grinder (4) and the increment pin (5) There are two magnets (6) in the gear wheel; at every rotation these induce two pulses to a Hall sensor, which in turn transmits them to the electronic system.

No coffeeA low coffee bean level is detected by the Hall sensor, after variations in the pulse frequency (with or without coffee). If there are no coffee beans (operation while empty), the number of rotations – and therefore the number of pulses – will be greater.t1 = no coffee indication

If, however, there are coffee beans, the number of rotations will be lower due to the force created by the grinding.t2 = no indication

t3 and t4 = this measurement is performed at the end of each grinding process

Dose quantity adjustmentThe dose quantity is adjusted in accordance with the pulses detected (number of rotations proportional to the selected fl avor – mild, medium or strong).Coffee grinder blockageIf the coffee grinder becomes blocked for any reason, pulses will no longer be transmitted to the electronic system and the grinder will come to a stop.

05



4.7. Dose self-learning (SAS)

06

The aim of this function is to automatically regulate the average dose of ground coffee (SELF-LEARNING); this takes place with an algorithm based on three pieces of data that the machine receives via the card:

1. Number of coffee grinder pulses during the grinding cycle.2. Max. average value of the power consumed by the gear motor during the coffee brewing cycle.3. Aroma selected by the user.

The algorithm compares the maximum average value of the power consumed by the gear motor with the value listed in the table for the selected aroma, in order to calculate the new grinding pulse value for the next coffee produced.If the power consumption value is less than the minimum current value, the grinding pulses will be increased by 2.If the power consumption value is greater than the maximum current value, the grinding pulses will be decreased by 4.If the power consumption value falls within the “over-torque” interval, the product will be dis-pensed and the grinding pulses will be decreased by 10.If the power consumption value falls within the “abort cycle” interval, the dreg will be expelled and the grinding pulses will be decreased by 10.If the “pre-ground” fl avour is selected by the user, no modifi cation will be made.

This guarantees that, regardless of the coffee type used, the grinding level setting and the wear on the grinders, the ground coffee dose always remains constant.

Important:For perfect operation, machine adjustment should take place in the area of the fi elds highlighted in green (A, B, C). When the type or brand of coffee is changed, there may be variations in the size of the beans and their stickiness or roasting level. This leads to variations in power consumption (mA), with resulting excessive or insuffi cient doses (until the necessary adjustments have been made to compensate for this change).Caution: In the case of excessive dosage, powder may be expelled into the dreg drawer. This is not a fault, but can occur during preliminary operation or after a service.

4.8. Water level detection (water tank)

“Water low” message (water reserve)

Function:The water level is monitored by a capacitative sensor, located one third of the way up the water tank wall.If the electronics assembly detects, by means of the sensor, that the amount of water in the tank has dropped below the above mentioned level, a water reserve remains available for the dispensing process underway (this will cover 200 fl ow meter pulses).The product dispensing process will then come to an end.If a dispensing cycle ends after the sensor has been triggered (in the reserve) then the display “Water low” continues to be displayed during the following dispensing cycle.

“Descaling” – message with water fi lter inserted(appliances with display only)

The water hardness is set on the basis of the regional water hardness analysis (1, 2, 3, 4).

Filter off:If the function is turned off the electronics assembly monitors the fl ow meter pulses, recording one pulse each turn.

Filter on:If the function is turned on the electronics assembly monitors the fl ow meter pulses, recording one pulse every two turns.

“Change water fi lter” message The electronics assembly uses the fl ow meter impulses to keep track of the amount of water which has fl owed through; after the specifi ed amount (set in accordance with the water hardness level), the “Replace fi lter” message appears.
